Science
Mechanism of Action
This ferment functions through multiple pathways to improve skin health. It is abundant in antioxidants, vitamins, and minerals, which combat free radical damage and mitigate signs of aging. The fermentation process transforms larger proteins into smaller, bioavailable peptides, facilitating deeper penetration for enhanced hydration, improved collagen production, and increased elasticity. It also contains bioactive peptides with noted antioxidant and anti-inflammatory capabilities. Furthermore, the ingredient supports a balanced skin microbiome, strengthening the skin's natural defenses against irritation. It actively inhibits melanin synthesis, contributes to collagen production, and reduces MMP-1 expression. By stimulating lactic acid, it provides gentle exfoliation, and the fermentation process itself reduces potential irritants, promoting superior skin tolerance.

Key findings
- 01 In a 30-day trial, an alcohol-free solution of rice bran ferment demonstrated a 9.29% improvement in skin whitening and a 44.31% improvement in moisturization.
- 02 Over a 30-day period, a 15% concentration in an alcohol-free solution showed a 5.36% enhancement in whitening and a 20.48% increase in moisturization.
- 03 A 10% alcohol-free rice bran ferment solution improved whitening by 3.69% and moisturization by 7.68% after 30 days. Additionally, a lotion with 10% fermented black rice bran extract significantly reduced melanin and erythema in 34 female subjects over 14 days.

Stability
The fermentation process inherently contributes to a more stable, pH-balanced ingredient. While specific optimal pH ranges for the final ingredient's stability are not detailed, the manufacturing process itself likely involves optimized pH conditions.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of rice-derived ingredients, including Rice Bran Extract, for use in cosmetics at current concentrations. These ingredients, particularly protein hydrolysates, are generally regarded as non-allergenic and do not exhibit acute toxicity, skin, or ocular irritation, or sensitization.
